Other than some basic brand characteristics, like: Salomon, Ride, and Forum are known for smaller footprints (this comes in handy if you have a size 11-12, and want to ride a smaller width board). Burton's have a taller instep, which can help if your foot sometimes goes numb in the toes from too much pressure in the instep. etc.
Other than that, TRY THEM ON!! Everyone's foot is different, and there is no way for us to tell you what is going to feel right for you.
